FIBER-SEPABATING MACHINE.

Application filled March 6, 1924. Serial No. 697,361.

To all whom it may concern:

Be it known that I, SnBAsrrANo MURABITO, a citizen of Italy, residing at Methuen, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Fiber-Separating Machines, of which the following is a specification.

This invention relates to machines for separating the larger and smaller locks of wool, one from the other and for separating dirt and shorts from both.

In handling wool, it is first sorted and separated into the different grades. It is then put in a chute which conveys it to a travelling belt or apron provided with prongs or teeth which pick up the larger locks or fleeces and delivers them to a washing machine. The shorts, smaller locks and dirt fall from the belt and are gathered up to be again separated and cleaned.

It is for use with such types of stock, and others of a similar nature that my machine is useful. Such material is more or less oily and clinging so that it is not readily separated.

At present it is manipulated by hand, and the dirt is to a certain extent removed by hand screens. This process is slow and expensive.

My machine can be operated by one person and separates much more than two or three can separate by hand.

It consists substantially of a series of reciprocating screens with advancing or stirring mechanism which causes the stock to travel while it is being shaken up. Provision is made whereby the large stock will fall ofi' from the end of a large screen while the small and medium stock will drop through it on to a medium screen.

The medium stock will drop off from the end of the medium screen and the small stock and remaining dirt will drop through this screen.

In the drawings, Fig. 1 is a front elevation of the complete machine, some parts being broken away to show the interior construction.

Fig. 2 is a sectional view similar to Fig. 1, on section line 2-2 of Fig. 3 showing the front of the frame removed, and exposing the interior parts, and with certain parts of the back frame broken away to expose the driving mechanism.

Fig. 3 is a plan view of the machine.

Fig. 1 is a sectional elevation on line of 1. l

A represents the frame of the machine which includes an enclosure having a bottom 100, sides 101 and 102, front 103 and back 10 1.

B represents a feed hopper having a back wall 107, floor frame 108, side walls 109 and 110 anda lip 7 at the bottom of an open side. This hopper has a fine screen C, forming most of its floor, made of a frame 52 with wires 53, all of which can be removed for cleaning.

The stock can be dropped into this hopper vB through a chute P and, as it is agitated by the operator, some of the dirt 1, falls into the chute D while the rest of the stock is gradually pushed along over lip 7 and drops on the sloping, reciprocating cross screen F which extends up under lip ,7. This screen F is carried in a frame E which is slidable in bearings 20 and 21, and is caused to re ciprocate by an arm 77 connected therewith by a pin 79 which passes through slot 78 in side 103, said arm being pivoted at 7 1, to a gear 76, carried by a spur shaft 73.

I provide advancing mechanism G which is shown as comprising side frames 30, 30, downwardly from which extend teeth 31 proximate screen F. This advancing mechanism is shown as being given a circular motion in the direction of the arrows by means of the rocker shafts 33 and 133, which have elbows 32 and 132, which extend through the sides 30, 30, in such a manner that as the shafts 33 and 133 revolve, the teeth 31, of the advancing mechanism G travel down close to screen F then lift up and over to repeat the process. The cross bars 130, 130, strengthen the construction.

At the end of this coarse screen E, is a hopper H which receives the large stock 3 while the smaller stock drops on to a sloping, reciprocating medium screen K positioned under screen E. This includes a re movable medium screen L carried by framework 51 and formed with wires 50.

This screen K is caused to reciprocate by means of a pin 84 which extends through a slot 85 in side 103 which is carried by arm 83, pivoted at 81 to a gear 80, carried by spur shaft 82.

The advancing mechanism M for this screen comprises two endless belts 40, 40, which travel over rollers 42, 42, driven by shafts 4:3 and 44, having between them the arms 41, 41, arranged so that they will travel close to screen K. Under this screen is a hopper N which receives what is left of the dirt while the small 5 looks 4 are dropped into another hopper O.

The driving mechanism for the screens, and the advancing devices include loose pulley and fast pulley 61 on main drive shaft 62 which extends across the machine and carries gear 7 5 which engages and drives gears 76 and 80, which operate the reciprocating screens.

Shaft 62 also carries the pulley 63, which through belt 64 drives pulley 65 carried by one end of roll shaft 44, which drives roll 42, which drives the advancing mechanism M and also carries a pulley 66, which by means of cross belt 67 drives pulley 68 on shaft 133 at the other end of which is a pulley 69, which through endless belt 70, drives pulley 71 on shaft 33, whereby the advancing mechanism G is operated.

Obviously, the dirt hoppers might be omitted and the different classes of stock allowed to fall on the ground and obviously the slope of the screens might be increased or decreased so that they would be practically level in accordance With the character of the stock as the advancing mechanism will cause the stock to progress at a rate determined by the size of the pulleys employed.

The feed hopper B might have a solid floor instead of a screen or the stock might be fed directly on to the top screen.

I claim:

1. In a wool fiber separating machine, the combination with a frame; of a feed hopper supported thereby having an open side with a delivery lip and a line screen as its floor; a dirt hopper thereunder; a sloping, reciprocating coarse screen which extends from under said lip; advancing mechanism arranged to intermittently advance the stock along said screen; a hopper to receive the large stock from said screen; a sloping reciprocating medium screen positioned under said coarse screen; advancing mechanism arranged to advance the stock along said screen; a hopper at the end thereof to receive the medium stock therefrom; and a dirt hopper under said medium screen; together with means to reciprocate the screens and to operate the advancing means.

In a wool fiber separating machine, the combination with a frame; of a feed hopper supported thereby having an open side with a delivery lip and a fine screen as its floor; a sloping, reciprocating coarse screen which extends from under said lip; advancing mechanism arranged to intermittently advance the stock along said screen; a sloping reciprocating medium screen positioned on der said coarse screen; advancing mechanism arranged to advance the stock along said screen; and means to reciprocate the screens and to operate the advancing means.

3. In a wool fiber separating machine, the combination with a frame; of a feed hopper supported thereby having an open side with a delivery lip and a fine screen as its floor; reciprocating coarse screen which extends from under said lip; advancing mechanism arranged to advance the stock along said screen; a reciprocating medium screen positioned under said coarse screen; advancing mechanism arranged to advance the stock along said screen; and means to reciprocate the screens and to operate the advancing means.
